Patient Factors Associated With Higher Expectations From Foot and Ankle Surgery.

Background: Few authors have investigated patients’ expectations from foot and ankle surgery. In this study, we aimed to examine relationships between patients’ preoperative expectations and their demographic and clinical characteristics. We hypothesized that patients with more disability and those with anxiety or depressive symptoms would have greater expectations. Methods: All adult patients scheduled for elective foot or ankle surgery by 1 of 6 orthopaedic foot and ankle surgeons were screened for inclusion over 8 months. Preoperatively, all patients completed the Hospital for Special Surgery Foot & Ankle Surgery Expectations Survey in addition to the Foot & Ankle Outcome Score (FAOS), Short Form (SF)–12, Patient Health Questionnaire (PHQ)–8, Generalized Anxiety Disorder 7-item scale (GAD-7), and pain visual analog scale (VAS). The expectations survey contained 23 expectations categories, each with 5 answer choices ranging from “I do not have this expectation” to “complete improvement” expected. It was scored from 0 to 100, with higher scores indicating more expectations. Differences in expectations relating to numerous patient demographic and clinical variables were assessed. In total, 352 patients with an average age of 55 ± 15 (range, 18-86) years were enrolled. Results: Expectations scores were not related to age (P = .36). On average, women expected to achieve complete improvement more often than men (P = .011). Variables that were significantly associated with higher expectations scores (P < .05) included nonwhite race, use of a cane or other assistive device, and greater medical comorbidity. Worse function and quality of life (as assessed by all FAOS subscales and the SF-12 physical and mental components), more depressive and anxiety symptoms, and higher pain VAS scores were associated with higher expectations scores and more expectations (P < .01 for all). Conclusions: The results of this study may help inform surgeons’ preoperative discussions with their patients regarding realistic expectations from surgery. Generally, patients with worse function and more disability had higher expectations from surgery. Addressing these patients’ expectations preoperatively may help improve their ultimate satisfaction with surgery. Level of Evidence: Level II, cross sectional study.

Development of an Expectations Survey for Patients Undergoing Foot and Ankle Surgery

Background: Many authors have reported on patient satisfaction from foot and ankle surgery, but rarely on expectations, which may vary widely between patients and strongly affect satisfaction. In this study, we aimed to develop a patient-derived survey on expectations from foot and ankle surgery. Methods: We developed and tested our survey using a 3-phase process. Patients with a wide spectrum of foot and ankle diagnoses were enrolled. In phase 1, patients were interviewed preoperatively with open-ended questions about their expectations from surgery. Major concepts were grouped into categories that were used to form a draft survey. In phase 2, the survey was administered to preoperative patients on 2 occasions to establish test-retest reliability. In phase 3, the final survey items were selected based on weighted kappa values for response concordance and clinical relevance. Results: In phase 1, 94 preoperative patients volunteered 655 expectations. Twenty-nine representative categories were discerned by qualitative analysis and became the draft survey. In phase 2, another 60 patients completed the draft survey twice preoperatively. In phase 3, 23 items were retained for the final survey. For retained items, the average weighted kappa value was 0.54. An overall score was calculated based on the amount of improvement expected for each item on the survey and ranged from zero to 100, with higher scores indicating more expectations. For patients in phase 2, mean scores for both administrations were 65 and 66 and approximated normal distributions. The intraclass correlation coefficient between scores was 0.78. Conclusion: We developed a patient-derived survey specific to foot and ankle surgery that is valid, reliable, applicable to diverse diagnoses, and includes physical and psychological expectations. The survey generates an overall score that is easy to calculate and interpret, and thus offers a practical and comprehensive way to record patients’ expectations. We believe this survey may be used preoperatively by surgeons to help guide patients’ expectations and facilitate shared decision making. Level of Evidence: Level II, cross-sectional study.

Comparative Outcomes Between Step-Cut Lengthening Calcaneal Osteotomy vs Traditional Evans Osteotomy for Stage IIB Adult-Acquired Flatfoot Deformity

Background: The forefoot abduction component of the flexible adult-acquired flatfoot can be addressed with lengthening of the anterior process of the calcaneus. We hypothesized that the step-cut lengthening calcaneal osteotomy (SLCO) would decrease the incidence of nonunion, lead to improvement in clinical outcome scores, and have a faster time to healing compared with the traditional Evans osteotomy. Methods: We retrospectively reviewed 111 patients (143 total feet: 65 Evans, 78 SLCO) undergoing stage IIB reconstruction followed clinically for at least 2 years. Preoperative and postoperative radiographs were analyzed for the amount of deformity correction. Computed tomography (CT) was used to analyze osteotomy healing. The Foot and Ankle Outcome Scores (FAOS) and lateral pain surveys were used to assess clinical outcomes. Mann-Whitney U tests were used to assess nonnormally distributed data while χ2 and Fisher exact tests were used to analyze categorical variables (α = 0.05 significant). Results: The Evans group used a larger graft size (P < .001) and returned more often for hardware removal (P = .038) than the SLCO group. SLCO union occurred at a mean of 8.77 weeks (P < .001), which was significantly lower compared with the Evans group (P = .02). The SLCO group also had fewer nonunions (P = .016). FAOS scores improved equivalently between the 2 groups. Lateral column pain, ability to exercise, and ambulation distance were similar between groups. Conclusion: Following SLCO, patients had faster healing times and fewer nonunions, similar outcomes scores, and equivalent correction of deformity. SLCO is a viable technique for lateral column lengthening. Level of Evidence: Level III, retrospective cohort study.

Measuring Joint Flexibility in Hallux Rigidus Using a Novel Flexibility Jig

Background: The flexibility of the first metatarsophalangeal (MTP) joint in patients with hallux rigidus (HR) has not been studied. Compared to measuring range of motion alone, measures of joint flexibility provide additional information that may prove useful in the assessment of HR. The purpose of this study was to assess the flexibility of the hallux MTP joint in patients with HR compared to controls using a novel flexibility device. Methods: Fifteen patients with Coughlin stage II or III HR and 20 healthy controls were recruited prospectively. Using a custom flexibility jig, each of 2 raters performed a series of seated and standing tests on each subject. Dorsiflexion angle and applied torque were plotted against each other to generate 5 different parameters of flexibility. Differences between (1) HR patients and controls and (2) the sitting and standing testing positions were assessed with t tests. Intrarater test-retest reliability, remove-replace reliability, and interrater reliability were assessed with intraclass correlation coefficients (ICCs). Results: Patients in the HR group were older than patients in the control group (P < .001) and had lower maximum dorsiflexion (P < .001). HR patients were less flexible as measured by 3 of the 5 flexibility parameters: early flexibility (first 25% of motion; P = .027), laxity angle (P < .001), and torque angle (P = .002). After controlling for age, only laxity angle differed significantly between HR patients and controls (P < .001). Generally, patients were more flexible when seated compared to standing, with this effect being more marked in HR patients. All parameters had good or excellent intra- and interrater reliability (ICC ≥ 0.60). Conclusions: Hallux MTP joint flexibility was reliably assessed in HR patients using a flexibility device. Patients with HR had decreased flexibility of the hallux MTP joint compared to control patients. Level of Evidence: Level II, prospective comparative study.

Correlation of Clinical Evaluation and Radiographic Hindfoot Alignment in Stage II Adult-Acquired Flatfoot Deformity:

Background: Previous work has demonstrated that the amount of radiographic hindfoot correction required at the time of adult-acquired flatfoot deformity (AAFD) operative treatment can be predicted by the amount of radiographic deformity present before surgery. Successful outcomes after reconstruction are closely correlated with hindfoot valgus correction. However, it is not clear if differences exist between clinical and radiographic assessment of hindfoot valgus. The purpose of this study was to evaluate the correlation between radiographic and clinical evaluation of hindfoot alignment in patients with stage II AAFD. Methods: Twenty-nine patients (30 feet) with stage II AAFD, 17 men and 12 women, mean age of 51 (range, 20-71) years, were prospectively recruited. In a controlled and standardized fashion, bilateral weightbearing radiographic hindfoot alignment views were taken. Radiographic parameters were measured by 2 blinded and independent readers: hindfoot alignment angle (HAA) and hindfoot moment arm (HMA). Clinical photographs of hindfoot alignment were taken in 3 different vertical camera angulations (0, 20, and 40 degrees). Pictures were assessed by the same readers for standing tibiocalcaneal angle (STCA) and resting calcaneal stance position (RCSP). Intra- and interobserver reliability were assessed by Pearson/Spearman’s and intraclass correlation coefficient (ICC), respectively. Relationship between clinical and radiographic hindfoot alignment was evaluated by a linear regression model. Comparison between the different angles (RCSP, STCA, and HAA) was performed using the Wilcoxon rank-sum test. P values of less than .05 were considered significant. Results: We found overall almost perfect intraobserver (range, 0.91-0.99) and interobserver reliability (range, 0.74-0.98) for all measures. Mean value and confidence interval (CI) for RCSP and STCA were 10.8 degrees (CI, 10.1-11.5) and 12.6 degrees (CI, 11.7-13.4), respectively. The position of the camera did not influence readings of clinical alignment (P > .05). The mean HMA was 18.7 mm (CI, 16.3-21.1 mm), and the mean HAA was 23.5 degrees (CI, 21.1-26.0). Clinical and radiographic hindfoot alignment were found to significantly correlate (P < .05). However, the radiographic HAA demonstrated increased valgus compared to both clinical alignment measurements, with a mean difference of 12.8 degrees from the RCSP (CI, 11.0-14.5, P < .0001) and 11.0 degrees from the STCA (CI, 9.2-12.8, P < .0001). Conclusion: We found significant correlation between radiographic and clinical hindfoot alignment in patients with stage II AAFD. However, radiographic measurements of HAA demonstrated significantly more pronounced valgus alignment than the clinical evaluation. The results of our study suggest that clinical evaluation of hindfoot alignment in patients with AAFD potentially underestimates the bony valgus deformity. One should consider these findings when using clinical evaluation in the treatment algorithm of flatfoot patients. Level of Evidence: Level II, prospective comparative study.

Patients’ Expectations of Foot and Ankle Surgery: Variations by Diagnosis

Category: Patient expectations Introduction/Purpose: Patients’ expectations from orthopaedic surgery may strongly affect postoperative satisfaction and have been shown to relate to many different factors, including age, sex, functional status, and health. However, the diverse diagnoses in foot and ankle surgery may also influence expectations. While pain relief tends to be the predominant expectation of orthopaedic foot and ankle patients, there are certain expectations that may be more important for patients with certain diagnoses. In this study, we aimed to analyze differences in patients’ expectations among the major surgical diagnoses seen in foot and ankle practices. Methods: 352 patients undergoing elective foot and ankle surgery by six orthopaedic foot and ankle surgeons were enrolled over eight months. Patients completed the Foot & Ankle Surgery Expectations Survey preoperatively, as well as the Foot & Ankle Outcome Score (FAOS), Short Form (SF)-12, Patient Health Questionnaire (PHQ)-8, Generalized Anxiety Disorder 7-item scale (GAD-7), and pain visual analog scale (VAS). The expectations survey is scored from 0-100 with higher scores indicating greater expectations. Each of its 23 items can also be assessed independently. Differences in expectations scores between diagnoses were analyzed with t-tests and analysis of variance (ANOVA). Differences in the number of expectations and number of expectations with complete improvement expected were analyzed with Mann-Whitney U and Kruskal Wallis tests. Results: Patients with a diagnosis of ankle instability or osteochondral lesion (OCL) had higher expectations scores (p = 0.004) and more often expected complete improvement (p = 0.024) compared to patients with other diagnoses (Table). Patients with hallux valgus had lower expectations scores (p = 0.005) than patients with other diagnoses. Patients with mid- or hindfoot arthritis also had lower expectations scores (p = 0.006) and even more significantly, had an average of only 2.4 expectations with complete improvement expected, while all other patients averaged 8.4 (p < 0.001). Expectations that were relatively unique to specific diagnoses included increased shoe variety for hallux valgus and hallux rigidus, improved appearance for hallux valgus, and improved ability to run for exercise for ankle instability or OCL. Conclusion: Patients’ expectations of foot and ankle surgery vary widely by diagnosis. Higher expectations among patients with ankle instability/OCL may be related to worse functional and mental health status (Table). Lower expectations among patients with hallux valgus and mid- or hindfoot arthritis may be attributable in part to patients’ recognition of the difficulty of treating their condition. Preoperative counseling by their surgeons regarding realistic expectations may also be a factor. We can use the findings of this study to predict what expectations are most important to patients with different diagnoses and to guide how we counsel them prior to surgery.

Patients’ Expectations from Foot and Ankle Surgery: Relationships with Demographic and Clinical Characteristics

Category: Other Introduction/Purpose: Few authors have investigated patients’ expectations from foot and ankle surgery, and standardized means of assessing expectations are lacking. Managing patients’ preoperative expectations may help improve their ultimate satisfaction with surgery. In a previous study (in press), we developed a valid and reliable patient-derived expectations survey for patients undergoing foot and ankle surgery. In this study, we aimed to examine relationships between patients’ preoperative expectations and their demographic and clinical characteristics. We hypothesized that patients with more disability and those with anxiety or depressive symptoms would have greater expectations. Methods: All adult patients scheduled for elective foot or ankle surgery by one of six orthopaedic foot and ankle surgeons were screened for inclusion over eight months. Preoperatively, patients completed the Foot & Ankle Surgery Expectations Survey in addition to the Foot & Ankle Outcome Score (FAOS), Short Form (SF)-12, Patient Health Questionnaire (PHQ)-8, Generalized Anxiety Disorder 7-item scale (GAD-7), and pain visual analog scale (VAS). The expectations survey contains 23 expectations categories, each with five answer choices ranging from I do not have this expectation to complete improvement expected. It is scored from 0-100; higher scores indicate greater expectations. Differences in expectations score with categorical variables were assessed with t-tests and single factor analysis of variance (ANOVA). Differences in number of expectations and number of expectations with complete improvement expected were assessed with Mann-Whitney U and Kruskal Wallis tests. Relationships between expectations and continuous variables were assessed with linear regression. Results: 352 patients (average age 55 ± 15, range 18 to 86) were enrolled. Expectations were not significantly related to age. Women expected to achieve complete improvement more often than men (p = 0.011). Other factors significantly associated with higher expectations (p < 0.05) included non-Caucasian race, workers’ compensation, use of a cane or other assistive device, diagnosis of ankle instability or osteochondral lesion, and greater medical comorbidity (Table). Patients with a history of prior orthopaedic surgery were less likely to expect complete improvement. Worse function and quality of life (as assessed by all FAOS subscales and SF-12 physical and mental components), more depressive and anxiety symptoms, and higher pain VAS scores were associated with higher expectations scores and more expectations (p < 0.001 for all). Conclusion: The results of this study may help inform surgeons’ preoperative discussions with their patients regarding realistic expectations from surgery. Generally patients with worse function and more disability had higher expectations from surgery. Addressing these patients’ expectations preoperatively may help improve their ultimate satisfaction with surgery.

Measuring Joint Flexibility in Hallux Rigidus Using a Novel First Metatarsophalangeal Joint Flexibility Jig

Category: Midfoot/Forefoot Introduction/Purpose: Range of motion measurements of the first metatarsophalangeal joint (MTPJ) are an essential component in assessing and classifying hallux rigidus (HR). However, they provide little information about joint function and are limited by variability in technique. As an alternative, measuring joint flexibility can characterize intrinsic properties of the joint—aside from simply maximum dorsiflexion and plantarflexion—that may prove more clinically meaningful. No prior study has assessed hallux MTPJ flexibility in patients with HR. The purpose of this study was therefore to assess the reliability of a custom flexibility device and to compare flexibility between HR patients and controls. Methods: Fifteen patients with Coughlin stage II or III HR indicated for cheilectomy and 20 healthy controls were recruited prospectively. Each of two raters performed a series of seated and standing tests on each subject with the device. Dorsiflexion angle and applied torque were plotted against each other to generate a flexibility curve. “Early flexibility” and “late flexibility” were defined as the slope of the curve in the first 25% and last 25% of motion, respectively. From these two parameters, three additional parameters were calculated: laxity angle, laxity torque, and torque angle (Figure). Differences between (1) HR patients and controls and (2) sitting and standing testing positions were assessed with t-tests. Intra-rater test-retest reliability, remove- replace reliability, and inter-rater reliability were assessed with intraclass correlation coefficients (ICCs). Results: Patients in the HR group were older than patients in the control group (p < 0.001) and had significantly lower maximum dorsiflexion (p < 0.001). HR patients were less flexible as measured by three of the five flexibility parameters: early flexibility (p = 0.027), laxity angle (p < 0.001), and torque angle (p = 0.002). After controlling for age on seated measurements, only laxity angle and maximum dorsiflexion differed significantly between HR patients and controls (p < 0.001). Generally, patients were more flexible in the seated position than in the standing position, with this effect being more marked in HR patients. All parameters had good or excellent intra- and inter-rater reliability (ICC = 0.60). Conclusion: This is the first study to demonstrate a reliable method of measuring first MTPJ flexibility in patients with HR. We found that flexibility, even early in the arc of motion, is impaired in patients with HR. Moreover, significant differences between sitting and standing measurements suggest that soft tissue tension may be a major contributor to this finding. We do not know yet how flexibility of the joint relates to symptomatology, or if the surgeries performed for HR affect flexibility. Further research will be required to determine the clinical utility of these measurements.

The Utilization of Internet Resources by Foot and Ankle Patients

Background: It is critical for patients seeking foot and ankle care to have access to quality online resources, as the treatment of their conditions may involve the use of a variety of diagnostic and therapeutic modalities with which they are unfamiliar. This study was performed to enhance our understanding of if and why patients use Internet-based educational materials, to identify trends in utilization, and to delineate the patient-perceived attributes of quality resources. Methods: Questionnaires were distributed to 150 adult foot and ankle patients. The questionnaire consisted of demographic and Internet utilization questions. Statistical analysis was performed to determine the frequency of responses for each question and the relationship between demographics and Internet usage. Results: Younger patients were more likely to use the Internet (P= .006). However, there were no other significant differences in demographic attributes between patients who did (76%) and did not (24%) utilize the Internet (P <.05). Of the participants who didn’t search the Internet about their condition, the most commonly cited reason was they preferred to receive information directly from their physician (47%). Among Internet users, most found the quality of resources to be good or very good (75%). However, many patients were unsure of the specific websites they accessed (66%) and if materials were AOFAS sponsored (18%). When asked about the attributes of a reliable website, patients felt that physician and/or medical society endorsement were most important (52% and 46%, respectively). Conclusion: Although physician and medical society endorsement positively shape patients’ opinions of online education materials, patients often struggle in remembering the site they visited and if it was sponsored by a certain society. Despite this, patients are generally satisfied with online foot and ankle education resources. Future works must assess whether patient and physician perceptions of quality Internet resources are correlated. Level of Evidence: Level IV, case series.

Orthopaedic Foot and Ankle Patient Comprehension An Analysis of Risk Factors for Limited Understanding

Category: Other Introduction/Purpose: Individuals with inadequate health literacy and limited comprehension may lack the skills needed to make informed decisions about their health. They are also at risk for inferior treatment outcomes and are more likely to express dissatisfaction with their care. Unfortunately, the Institute of Medicine has declared low health literacy a “silent epidemic”, as approximately 50% of Americans are afflicted. Because foot and ankle disorders are common, often disabling, and at times utilize a variety of diagnostic and therapeutic modalities unfamiliar to patients, it is critical that we gain insight into patients’ foot and ankle comprehension. As such, we developed a novel questionnaire, the Foot and Ankle Literacy Survey (FALS), to evaluate this and the relationship between demographic factors and foot and ankle specific comprehension. Methods: The 14 question FALS (Figure 1A) was developed by our study group and was distributed to a consecutive series of 206 English-speaking adults presenting for first visits, immediate pre-operative evaluations, or one of a number of post-operative or follow-up visits in the foot and ankle practices of our senior authors and the ambulatory care clinic of an academic, urban medical center. The questionnaire’s content was based on the following four categories: 1) terminology, 2) anatomy, 3) conditions and treatment, and 4) perioperative considerations. These categories were chosen following our group’s review of the most commonly emphasized themes within the American Orthopaedic Foot and Ankle Society’s internet-based patient education website, FootCareMD.org. Participants completed the FALS and a demographic survey. Both overall and categorical performance were evaluated as a function of demographic characteristics via Wilcox Rank Sum, Kruskal-Wallis and McNemar’s testing. The level of significance for all tests was set at P < 0.05. Results: Participants’ demographic characteristics are presented in Figure 1B. The mean FALS score was 9.88 ± 2.67 out of a possible 14 points. Participants performed significantly worse on the conditions and treatment subsection as compared to the others (P < 0.05). Significantly better FALS performance correlated with race (Caucasian, P < 0.001), higher levels of education (College degree or higher, P < 0.001), visit type (Pre-operative evaluation, P < 0.002), and a current or previous healthcare occupation (P=0.008) (Figure 1B). Additionally, of those patients who had previously seen a provider (orthopaedic surgeon, podiatrist, orthopaedic surgeon and podiatrist, other provider) for a foot and ankle complaint, a significantly higher score was observed in patients who saw an orthopaedic surgeon versus other types of providers. Age, gender and anatomic region did not correlate with FALS scores. Conclusion: Patient comprehension of foot and ankle related terminology, anatomy, conditions, treatment, and perioperative issues is critical for successful encounters between orthopaedic foot and ankle surgeons and patients. This study has identified race, education, occupation, prior evaluation by an orthopaedic surgeon, and visit type as factors that significantly correlate with comprehension. With such knowledge, patient education can be focused on those most in need, an approach that we hope will improve health literacy and optimize outcomes. Admittedly, future research is pivotal and must identify the most effective means of educating patients and objectively evaluate the relationship between outcomes and patient comprehension.
